You people are absolutely, completely, and totally deranged. There's nothing more pathetic than whining fans who didn't get their top choice in U2 tickets.
And this happens EVERY tour. Please don't delude yourself into thinking this is all somehow new. U2 has been the biggest band in the world for about 20 years, and every tour, there are way more fans than there are tickets. Unfortunately, not everyone can go to the shows. It sucks, yes, but that's life. There are many, many, many other people just like you who love U2 and who got tickets today. But you didn't. I know that's hard to deal with, and I know you feel wronged, and I know you probably love the band so much that you want to sue somebody, but take a deep breath and chill out. It's only rock n' roll. Crazy shit happens. There will be a DVD.
